**Abdominal Aortic Aneurysm (AAA) Study Overview** This study looks at how safe and effective a new product called **IMPEDE-FX RapidFill** is for shrinking a bulge in a large blood vessel in the tummy area, called an **abdominal aortic aneurysm (AAA)**. This product is used along with a common procedure called **endovascular aneurysm repair (EVAR)**, which involves placing a stent (a tube-like device) to support the weakened blood vessel. The study is for people who need this procedure and meet certain health criteria. **Eligibility Criteria**: Participants must be 18 or older and eligible for the EVAR procedure on an aneurysm of a certain size. They should not have more than half of the aneurysm filled with a clot, and the bulge must be a specific size. Certain health problems or participation in other studies may exclude someone from joining. **Key Points**: - **Length and Visits**: Regular follow-ups are needed to check on the aneurysm and overall health after the procedure. - **Risks**: Standard risks associated with stent placement and any additional risks from using the new product. - **Compensation**: Participants may receive compensation for time and travel expenses. This study helps understand if this new product can help make aneurysms smaller in a safe way.
